JOHN L. DIEHM, OF PHILADELPHIA, PENNSYLVANIA.

FUEL-HOLDER.

Application filed July 24, 1914.

To all whom it may concern Be it known that I, JOHN L. DIEHM, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Fuel-Holders, of which the following is a specification.

The invention relates to an improved fuel saver, comprehending specifically a device adapted to be manually introduced into a fire box above the dead fuel resting on the grate, so as to act as a support for the live fuel during grate shaking operation, whereby the fire is cleared without waste of fuel.

The invention comprehends a plate ele ment adapted to be manually introduced between the dead and live fuel in the fire box and to effectively act as a support for such live fuel, so that the grate shaking operation will in no wise disturb the live fuel, the plate element being readily introduced and removed to insure efficient operation.

The invention in the preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which:-

Figure 1 is a broken sectional view partly in elevation illustrating the application of the improvement to a furnace type of heater. Fig. 2 is a horizontal sectional view of the same. Fig. 3 is a perspective view of the supporting attachment for the furnace type of heater. Fig. 4 is a perspective view of the deflector for use with the attachment. Fig. 5 is a perspective view of one of the guide plates. Fig. 6 is a perspective view of the gate.

In Figs. 1 to 6, I have shown the attachment as designed for heaters of the furnace type, involving the usual fire box 31, ordinarily circular, in which is arranged the usual rocking or semi-rotary grate 32. For the purpose of the present invention, the usual front opening of the furnace is provided with the supporting member involving an approximately rectangular casing 33, open at the front side, as at 82' and provided with edge flange 33, conforming to the curvature of the furnace and adapted to be secured thereto, as at 36.

Secured within and against each side wall of the casing is a plate 34, having a guide shelf 35 projecting at right angles thereto about mid-height the plate, the upper edge Specification of Letters Patent.

of the plate being provided with a stop flange 86. The guide shelf extends the full length of the plate, while the stop flange extends a portion of said length, the upper edge of the plate in rear of the flange being formed with a recess 37 and in rear of the recess with an angular depression 38. With the supporting member secured to the furnace, the plate 34: extends within the interior of the furnace, as shown in Fig. 1, the bottom of the casing 33 being down wardly and inwardly inclined as at 39, and the forward portion of the lower edge of each plate being correspondingly inclined at 40, so that the parts interfit. A. gate 41 comprising a plate having the lower edge beveled at 12, is provided with trunnions as, so that the gate may be swung in the recesses 37 of the plates 34:, so that the gate closes the space in rear and above the guide shelves 35. As the gate is supported within the interior of the furnace and as it is necessary to protect this portion of the device against being rendered inoperative by the accumulation of fuel or ashes thereon, I provide what 1 term a deflector M comprising a plate of sufficient length to bridge the space between the plates 34, the inner edge of the deflector being formed with a projection 45 to seat in and accurately fit the depressions 38. Wedge keys 46 are forced between the upper surface of the plate and the adjacent underlying edge of the furnace wall to fix the plate in position. In this form, the fuel saver attachment comprises a plate 47 of a width corresponding to the distance between the supporting plates 34:, having a length exceeding the transverse dimension of the fire box, so that when the attachment is in place, the forward edge of the plate extends beyond the furnace, as clearly shown in Figs. 1 and 2.

Pivotally supported upon the plate 47 adjacent the inner edge thereof, and preferably on the upper side, are wings 48, said wings being of aggregate width corresponding to that of the plate and pivotally connected at their adjacent edges, as shown. The forward portions of the wings are connected by links 49 with the adjusting bar 50 slidably mounted in guides 51 secured upon the plate 47, the forward end of the adjusting bar being provided with a handle 52.

in use, in this form of the device, the attachment, with the wings in closed position, is introduced into the furnace through the supporting member, being supported for movement upon the ledges 35, and the inward movement of the attachment being continued until the lugs 53 carried thereby engage the stop flanges 36. In this movement of the attachment, the gate 4:1 is displaced, as shown in Fig. 1, and after the attachment has been inserted to the length. desired, the wings 48 are spread by inward movement of the adjusting bar 50. This operates to extend the width of the plate so as to support the live fuel practically throughout the extent of the fire box, permitting the grate to be operated to the desired extent to free fuel from the ashes and other dead accumulation. The supporting member is provided with a door 5 f by which the opening may be closed when desired.

From the above description, it will be obvious-that I have provided a fuel saver attachment adapted for ready cooperation with any type of stove or furnace and which in use, will operate to effectively separate the ashes and other dead accumulation from the live coals in the fire box and support the latter for any desired length of time to permit complete removal of such refuse, either by operation of the grate or any other desirable manner. The attachment thus acts as fuel saver, as it absolutely prevents the possibility of any live coals or live fuel from being delivered to the ash pit unconsumed and at the same time places within reach of the user a simple and complete means of always maintaining the fire in bright, clean condition.

Copies of this patent may be obtained for It is of course to be understood that the parts of the improved attachment described are metallic and of sufficient strength and it for cooperation with aparticular or gen-' eral type of stove or furnace, so long as the ends aimed at are accomplished.

What is claimed is 1. A fuel saver comprising pivoted plate elements for cooperation with the fuel body of theheater, said plate elements being so pivoted as to have a horizontal rectilinear motion toward and away from each other, a handle, link mechanism between said handle and plate elements, and arectilinear plate for guiding the operation of said link mechanism. i

2. A fuel saver comprising pivoted plate elements for cooperation with the fuel body of the heater, said plate elements being so pivoted as to have a horizontal rectilinear motion toward and away from each other, a handle, link mechanism between said handle and plate elements, a rectilinear plate for guiding the operation of said link mechanism, and means for slidably supporting said rectilinear plate.

In testimony whereof I aiiix my signature in presence of two witnesses.
